Description

배전용 전주의 배전선 탄성 지지완철{Elastic support of distribution lines on power distribution poles}Elastic support of distribution lines on power distribution poles

본 발명은 배전용 전주의 배전선 탄성 지지완철에 관한 것으로서, 보다 상세하게는 탄성체인 C형신축스프링판과 애자체 및 상하부텐셔너를 구비하여 최소한의 간단한 구조로 계절의 온도 변화에 따른 배전선의 길이변화에 따른 인류바인드선의 장력에 보다 신축적으로 대응할 수 있어 작업자의 조립작업이 손쉽고 그로 인해 작업시간 및 시공비용이 크게 절감되는 배전용 전주의 배전선 탄성 지지완철에 관한 것이다. The present invention relates to an elastic support arm of a distribution line of an electric pole for distribution, and more particularly, it has a minimal and simple structure including an elastic C-shaped expansion spring plate, an insulator, and upper and lower tensioners, and changes in the length of a distribution line according to seasonal temperature changes It relates to an elastic support arm of a distribution line for distribution poles that can respond more flexibly to the tension of the human bind wire according to the present invention, which makes assembly work easier for workers, thereby greatly reducing work time and construction cost.

일반적으로 저압 인류애자는 비교적 저압전류가 흐르는 배전선 또는 통신선 등을 절연 고정하기 위한 것으로서, 도 5에 도시한 바와 같이, 인장클램프(200)에 고정되는 전선(300)을 잡아 지지하게 된다. 이때, 상기 인장클램프(200)는 인류바인드선(400)을 매개로 저압 인류애자(100)의 애자체(130)와 연결되는데, 통상적으로 애자체(130)는 전주(10) 등에 고정되는 랙크(120)에 인류바인드선(400)과 수직방향으로 위치하는 고정축(131)으로 단단히 고정된다. 즉, 상기 인류바인드선(400)이 애자체(130)를 감싸듯 고정되는 것이다. 미 설명된 인출번호 '110'은 벨트를 인출한 번호로, 애자체(130)를 지지하는 레크(120)와 연결되고, 전주(10)를 감싸면서, 인류애자(100)를 상기 전주(10)에 고정한다. In general, the low voltage insulator is for insulating and fixing a distribution line or a communication line through which a relatively low voltage current flows, and as shown in FIG. 5 , holds and supports the electric wire 300 fixed to the tension clamp 200 . At this time, the tension clamp 200 is connected to the insulator 130 of the low-pressure human insulator 100 via the human binding wire 400, and the insulator 130 is typically a rack fixed to the electric pole 10, etc. It is firmly fixed to the human binding line 400 and the fixed shaft 131 located in the vertical direction at 120 . That is, the human binding wire 400 is fixed as if wrapped around the insulator 130 . Unexplained withdrawal number '110' is a number drawn out of the belt, is connected to the rack 120 supporting the insulator 130, and wraps the electric pole 10, while the human insulator 100 is transferred to the electric pole 10 ) is fixed to

한편, 전선(300)은 온도에 따라 팽창과 수축을 반복하는 재질이므로, 하절기에는 높은 외부온도에 의해 팽창하면서 하방으로 늘어질 수 있다. 그런데, 전선(300)이 늘어질 경우엔, 전선(300)의 장력이 약해지면서 애자체(130)를 감싸는 인류바인드선(400)의 조임이 완화되고, 전선(300)의 하중에 의해 하방으로 지속적인 힘을 받게 되므로, 애자체(130)의 둘레부를 감싸는 인류바인드선(400)이 애자체(130)로부터 미끄러져서 분리되는 문제점이 있었다. On the other hand, since the electric wire 300 is a material that repeats expansion and contraction according to temperature, it may stretch downward while expanding due to a high external temperature in summer. However, when the electric wire 300 is stretched, the tension of the electric wire 300 is weakened and the tightening of the human bind wire 400 surrounding the insulator 130 is relieved, and downward by the load of the electric wire 300 . Since it receives continuous force, there was a problem in that the human bind wire 400 surrounding the periphery of the insulator 130 was slid and separated from the insulator 130 .

물론, 이를 대비해 애자체(130)의 둘레부에 오목홈을 형성시켜서 인류바인드선(400)이 쉽게 이탈하지 못하도록 할 수 있지만, 이는 완벽한 결합구조가 아니므로 이상고온에 의한 전선(400)의 팽창시에는 인류바인드선(400)이 애자체(130)로부터 이탈하여 분리되는 사고가 발생할 수 있었다. Of course, in preparation for this, a concave groove is formed in the periphery of the insulator 130 to prevent the human bind wire 400 from being easily separated, but since this is not a perfect coupling structure, the expansion of the wire 400 due to abnormal high temperature At the time, an accident in which the human bind wire 400 was separated from the insulator 130 could occur.

또한, 인류애자(100)에 고정되는 전선(300)은 비교적 고압의 전류가 흐르는 전선을 지지하는 현수애자와 충분한 거리로 이격 배치되어야 한다. 이는 저압의 전류가 흐르는 전선(300)이 고압 전선 주변에 발생하는 전자기장으로부터 쉽게 영향을 받을 수 있기 때문이다. 따라서, 종래에는 현수애자가 고정 배치되는 지지완철에는 인류애자(100)가 설치될 수 없었다. In addition, the electric wire 300 fixed to the human insulator 100 should be spaced apart from the suspension insulator for supporting the electric wire through which a relatively high-voltage current flows by a sufficient distance. This is because the electric wire 300 through which the low-voltage current flows can be easily affected by the electromagnetic field generated around the high-voltage electric wire. Therefore, in the prior art, the human insulator 100 could not be installed on the support arm in which the suspension insulator is fixedly arranged.

그러나, 고압 및 저압의 전선을 하나의 전주에서 별도 설치함으로서 전선의 설치작업은 물론 사용 부재수가 증가하는 문제점이 있었다. However, by separately installing high-voltage and low-voltage wires on one electric pole, there is a problem in that the number of members used as well as installation work of the wires increases.
